The purpose of this study was to analyze A characteristics on the left ventricular structure and function, and the artery blood flow change in women according to aerobic exercise particpation. The experimental group have been doing regular exercise, but the I group have not done regular exercise. According to the career of aerobic exercise, the experimental group have been classified into group II (less than three months of exercise), group Ⅲ (four years of exercise), and group IV (nine years of exercise). During the research, the left ventricular structure and its functional parameters have been examined by the ultrasonocardiograph. The artery blood flow parameters have been examined by TCD. As a result of the analysis of all the parameters of each examined group we can conclude as follows: 1. In the LVID, LVIDd showed significant difference between groups such as p<01. LVIDs showed significant difference between the experimental groups as well as the I groups such as p< .05. The order of LVPWd was group II, group II and group IV. The LVPWd of group IV was a little higher than others’. But there was no significant difference between groups (p >.05). The orders of LVPWs, IVSd and IVSs for the I groups were group II, group Ⅲ and group IV. Group IV's of three variables were higher than others', but there's no significant difference between groups(p>.05). 2. In the LVDV and LVSV of the left ventricle's parameters, there was significant difference between groups (p<.05). The LVmass, SV, EF, and HR were showed significant difference between groups(P<.01). The HR of group IV was the lowest as compared with that of the I group, so group IV was capable of using the inhaled oxygen more efficiently than other groups. 3. The PBV of group IV is the highest as compared with that of group II. There was significant difference between groups (p<.01). In the MBV group IV and group ID were the highest among them. There was significant difference between groups (p<.01). As a result of the consideration given above, those women who have participated in long-term aerobic exercise have their left ventricle's function enhanced as a result that the extra capacity of the left ventricles can be improved and the left ventricular structure has been strengthened in part, but the improvement of the left ventricular posterior wall thickness is thought to be dubious. But in addition to the improvement of those functions such as LVD, LVmass and SV, the efficiency of the arterial Wood circulation has been more improved. Therefore, some aerobic exercise programs appropriate to the physical capacity of women of various ages will be expected to be developed.

AbstractA Cu(II)‐Poly(terthiophene carboxylic acid) (pTTC)/Nafion modified glassy carbon electrode has been used for the chiral recognition and discrimination of d‐ and l‐prolines by the catalytic oxygen reduction process and the shape of crystals formed on the electrode surface. The cyclic voltammetry with the modified electrode in the presence of oxygen recognized d‐ and l‐form of prolines by exhibiting a difference in the peak potential and the peak current of the oxygen reduction. The effect of pH and proline concentration on the peak current and the peak potential of oxygen have been studied. The SEM studies on the nature of crystals formed on a proline‐Cu(II)pTTC complex. The oxidation state of the copper species present at the electrode surface was characterized by ESCA.
